Psychotronic Energy Scans
Description: This rote acts as a magickal early-warning system. It works though a method called psychotonic scanning, siphoning off a miniscule proportion of an area's energy and immediately returning it. Fluctuation in the total energy in the area are reflected in the energy of the sample. When something using energy such as an animal or an operating machinee nters, the amount of energy sampled changes, and the mage can observe the change.
System: The Mind 1 component is needed to keep the subconscious manual monitoring of the scan going. often some kind of expert system or an apprentice is given this duty instead. Many pages also add Prime 1 to detect shifts in quintessence levels as well, this reveals mages, talismans,and other quintessence-related changes in the area.
